CVBuffer

Overview

A CVBuffer serves as an abstract base class that defines how to interact with buffers of data. A buffer object can hold video, audio, or possibly other types of data. All the other buffer types within the Core Video framework, such as CVImageBuffer and CVPixelBuffer, derive from CVBuffer. You can use the CVBuffer programming interface on any Core Video buffer.
